NAME

6       abrt_selinux - Security Enhanced Linux Policy for the abrt processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the abrt processes via flexible manda‐
10       tory access control.
11
12       The abrt processes execute with the abrt_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep abrt_t
19
20
21

ENTRYPOINTS

23       The abrt_t SELinux type can be entered via the abrt_exec_t file type.
24
25       The default entrypoint paths for the abrt_t domain are the following:
26
27       /usr/sbin/abrt-harvest.*,     /usr/sbin/abrtd,     /usr/sbin/abrt-dbus,
28       /usr/sbin/abrt-install-ccpp-hook
29

PROCESS TYPES

31       SELinux defines process types (domains) for each process running on the
32       system
33
34       You can see the context of a process using the -Z option to ps
35
36       Policy governs the access confined processes have  to  files.   SELinux
37       abrt  policy  is  very flexible allowing users to setup their abrt pro‐
38       cesses in as secure a method as possible.
39
40       The following process types are defined for abrt:
41
42       abrt_t, abrt_dump_oops_t, abrt_handle_event_t, abrt_helper_t, abrt_retrace_worker_t, abrt_retrace_coredump_t, abrt_watch_log_t, abrt_upload_watch_t
43
44       Note: semanage permissive -a abrt_t can be used  to  make  the  process
45       type  abrt_t  permissive.  SELinux  does  not deny access to permissive
46       process types, but the AVC (SELinux denials) messages are still  gener‐
47       ated.
48
49

BOOLEANS

51       SELinux  policy  is  customizable based on least access required.  abrt
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run abrt with the tightest access possible.
54
55
56
57       If  you  want  to  determine  whether  ABRT  can  run  in the abrt_han‐
58       dle_event_t domain to handle ABRT event scripts, you must turn  on  the
59       abrt_handle_event boolean. Disabled by default.
60
61       setsebool -P abrt_handle_event 1
62
63
64
65       If you want to allow users to resolve user passwd entries directly from
66       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
67       gin_nsswitch_use_ldap boolean. Disabled by default.
68
69       setsebool -P authlogin_nsswitch_use_ldap 1
70
71
72
73       If you want to deny user domains applications to map a memory region as
74       both executable and writable, this  is  dangerous  and  the  executable
75       should be reported in bugzilla, you must turn on the deny_execmem bool‐
76       ean. Enabled by default.
77
78       setsebool -P deny_execmem 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If  you  want  to allow confined applications to run with kerberos, you
90       must turn on the kerberos_enabled boolean. Enabled by default.
91
92       setsebool -P kerberos_enabled 1
93
94
95
96       If you want to allow system to run with  NIS,  you  must  turn  on  the
97       nis_enabled boolean. Disabled by default.
98
99       setsebool -P nis_enabled 1
100
101
102
103       If  you  want to allow confined applications to use nscd shared memory,
104       you must turn on the nscd_use_shm boolean. Enabled by default.
105
106       setsebool -P nscd_use_shm 1
107
108
109

MANAGED FILES

111       The SELinux process type abrt_t can manage files labeled with the  fol‐
112       lowing  file  types.   The paths listed are the default paths for these
113       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

246       SELinux requires files to have an extended attribute to define the file
247       type.
248
249       You can see the context of a file using the -Z option to ls
250
251       Policy  governs  the  access  confined  processes  have to these files.
252       SELinux abrt policy is very flexible allowing users to setup their abrt
253       processes in as secure a method as possible.
254
255       EQUIVALENCE DIRECTORIES
256
257
258       abrt  policy  stores  data  with  multiple different file context types
259       under the /var/cache/abrt directory.  If you would like  to  store  the
260       data  in a different directory you can use the semanage command to cre‐
261       ate an equivalence mapping.  If you wanted to store this data under the
262       /srv dirctory you would execute the following command:
263
264       semanage fcontext -a -e /var/cache/abrt /srv/abrt
265       restorecon -R -v /srv/abrt
266
267       abrt  policy  stores  data  with  multiple different file context types
268       under the /var/run/abrt directory.  If you would like to store the data
269       in  a different directory you can use the semanage command to create an
270       equivalence mapping.  If you wanted to store this data under  the  /srv
271       dirctory you would execute the following command:
272
273       semanage fcontext -a -e /var/run/abrt /srv/abrt
274       restorecon -R -v /srv/abrt
275
276       abrt  policy  stores  data  with  multiple different file context types
277       under the /var/spool/abrt directory.  If you would like  to  store  the
278       data  in a different directory you can use the semanage command to cre‐
279       ate an equivalence mapping.  If you wanted to store this data under the
280       /srv dirctory you would execute the following command:
281
282       semanage fcontext -a -e /var/spool/abrt /srv/abrt
283       restorecon -R -v /srv/abrt
284
285       STANDARD FILE CONTEXT
286
287       SELinux  defines  the file context types for the abrt, if you wanted to
288       store files with these types in a diffent paths, you  need  to  execute
289       the  semanage  command  to  sepecify  alternate  labeling  and then use
290       restorecon to put the labels on disk.
291
292       semanage  fcontext  -a  -t  abrt_upload_watch_tmp_t   '/srv/myabrt_con‐
293       tent(/.*)?'
294       restorecon -R -v /srv/myabrt_content
295
296       Note:  SELinux  often  uses  regular expressions to specify labels that
297       match multiple files.
298

461
462
463       Note:  File context can be temporarily modified with the chcon command.
464       If you want to permanently change the file context you need to use  the
465       semanage fcontext command.  This will modify the SELinux labeling data‐
466       base.  You will need to use restorecon to apply the labels.

SHARING FILES

470       If you want to share files with multiple domains (Apache,  FTP,  rsync,
471       Samba),  you can set a file context of public_content_t and public_con‐
472       tent_rw_t.  These context allow any of the above domains  to  read  the
473       content.   If  you want a particular domain to write to the public_con‐
474       tent_rw_t domain, you must set the appropriate boolean.
475
476       Allow abrt servers to read the /var/abrt directory by adding  the  pub‐
477       lic_content_t  file  type  to  the  directory and by restoring the file
478       type.
479
480       semanage fcontext -a -t public_content_t "/var/abrt(/.*)?"
481       restorecon -F -R -v /var/abrt
482
483       Allow abrt servers to read and write /var/abrt/incoming by  adding  the
484       public_content_rw_t  type  to  the  directory and by restoring the file
485       type.  You also need to turn on the abrt_anon_write boolean.
486
487       semanage fcontext -a -t public_content_rw_t "/var/abrt/incoming(/.*)?"
488       restorecon -F -R -v /var/abrt/incoming
489       setsebool -P abrt_anon_write 1
490
491
492       If you want to allow ABRT to modify public files used for  public  file
493       transfer services., you must turn on the abrt_anon_write boolean.
494
495       setsebool -P abrt_anon_write 1
